Need a strap duplicator and/or transfer screw for 8-32 nutplate holes
I need to locate seven, 8/32 screw holes on the periphery of a 12" x 8" plate.
The nutplates are installed on the underside of 0.064 angle. I have to drill the holes in the plate to match the location of the nutplates.
I see strap duplicators for 10-32 (and #21, #30 and #40) and I see transfer screws for 10-32. But I don't see strap duplicators for 8-32.
Why is that?
I did see transfer screws for 8-32 at McMaster-Carr:

but I'm wondering if they are long enough such that the threads will fetch up solidly in the nutplate (and therefore center the point) , and sill have the point proud enough to make a solid mark.
I can't find dimensions of those transfer screws.
I also saw these:

and there are none for 8-32.
If anyone knows a source - or has a better idea for locating the holes - I'd appreciate the pointer.
Thanks!
